The slab sandwich starts with a plastic vapor barrier on the native soil followed by a layer of gravel that acts as a capillary break. Above the gravel is a layer of insulation topped by another plastic vapor barrier. Then, comes the rebar and finally tubing for the heated floor system. All that’s missing is the concrete – which should be poured in the next two weeks.
Since the last update, we have also cleared the area outside the north wall in preparation for the retaining wall that will be built there.
